Abstract:
In a telecommunication network, pilot signals are provided in orthogonal frequency division multiplexing frames to enable a single-carrier frequency division multiple access method to work substantially harmoniously with an orthogonal frequency division multiplexing access method in uplink. Each orthogonal frequency division multiplexing frame comprises a plurality of orthogonal frequency division multiplexing symbols. At least one pilot signal is placed within at least one existing orthogonal frequency division multiplexing symbol.
